COMBINED WATER- FILTER, STERILIZER, AND COOLER.

Application filed October 17, 1914.

To all whom it may concern:

Be it known that I, URBANE J. EwrNo, a citizen of the United States,residing at Uniontown, in the county of Fayette and State ofPennsvlvania, have invented certain new and useful Improvements inCombined T'Vater Filters, Sterilizers, and Coolers, of which thefollowing is a specification.

My invention relates to filters and designed more particularly forremoving sediment, bacteria, and other impurities from drinking water. v

The objects of my invention are first, to construct a water filter whichnot only is durable but cheap to manufacture, easily assembled or takenapart for cleaning and inspection and renewal of the filtering andpurifying materials. Second, to construct a filter in which the partsare so constructed and arranged that all the water in the filter willreadily pass out from the same, thus insuring no dead water space topocket the contaminated water after the faucet is opened to completelydrain the filter when not in use or to be taken apart for cleaning orinspection. l hird, to construct a corn bined filter, sterilizer andcooler, in which the parts are so constructed and arranged that thewater will pass through and over a maximum of filtering or softeningmaterial and in contact with a bacteria sterilizing surface within aminimum of space of the cooler, thereby insuring a large space forreceiving the water to be treated within a given sized combined filterand cooler. Fourth, to construct a combined filter and sterilizer inwhich the parts are regular in shape, easily stamped, out or shaped andassembled by ordinary skilled labor, in the minimum of time, therebyreducing the cost of manufacture and selling price to the lowest figurewithout reducing the efiiciency and capacity of the filter. Fifth, otherobjects and advantages of the invention will readily appear from thedetailed description to be hereinafter given.

The invention consists of structural features and relative arrangementsof the different elements comprising the filter, which will behereinafter more fully described and particularly pointed out in theappended claims.

In the accompanying sheet of drawing similar reference charactersindicate the same parts in the several figures in which Figure 1 is alongitudinal sectional view Specification of Letters Patent.

partly in elevation, of the bottom of a combined filter' and coolerprovided with my improvements; Fig. 2 is a transverse sectional viewtaken on line II1I of Fig. 1, and Fig. 3 is a perspective view of thesplit wire ring for retaining the woven asbestos pad on top of thefilter.

Referring to the drawings, 1 represents the outer cylinder or watercooler receptacle which may be made of any suitable material andprovided with any suitable and well known coating or lining to preventcorrosion, and an outer well known non-conducting sheathing, not shown.to insure the outer temperature from not affecting that Within thecooler.

A bottom 2 of the receptacle has secured thereto the usual legs 3, 3,and is provided preferably at its center section with a threaded opening4, which receives an outer depending threaded nipple 4', to which isattached. by means of an elbow, a horizontal outlet pipe 6, arrangedadjacent to the underside of the bottom 2, the outer end of said pipe 6being controlled bv a faucet 7.

Secured to the inner side of the bottom 2, by solder or other means andover the threaded opening 4, is a section of copper screen 5 to preventany of the filtering material from passing into the pipe 6.

Attached to the bottom 2, by solder or held in place by engagement witha ring 8, suitably secured to said bottom 2, is a ring 9, having aseries of perforations 10. said ring 9 being symmetrically placed withrespect to the opening 4, in the bottom 2. and subdivides the lowersection of the cylinder or receptacle 1, into a circular centralcompartment 11, surrounded by an annular compartment 12. Thecompartments 11 and 12 are filled with any form of granular waterpurifying materials such as animal or wood charcoal, or with anvsuitable purifying material, indicated in Fig. 1.

The upper and open end of the central compartment 11, is closed by animperforate removable cover 13, while resting on top of said cover 13,is a circular cover 14, of a diameter equal to the inner diameter of thecylinder or receptacle 1, said cover 14, being so constructed andarranged, that the outer annular section directly over the annularcompartment 12. is provided with perforations 15, while the centralcircular section over the cover 13 is preferably imperforate.

16 is an imperforate cover superimposed upon and being of the samediameter as the cover 14:, and is provided at its periphery with aseries of cut away sections 17 preferably semicircular in form as shownin Fig. 2.

Resting upon the cover 16 is an interwoven wire and asbestos circulardiaphragm 18 having an upturned edge or periphery l9, lying against theinner side of the receptacle 1 and firmly held in position down on thecover 16 and against the receptacle 1, by means of a split wire ring 20,having overlapping ends provided with upturned extensions 21, to begrasped by the fingers, to retract the ring 20, to disengage the samefrom the inner side of the receptacle 1, and enable the asbestos cover18, superimposed covers 14 and 16 to be removed to clean or renew thecharges of charcoal or softening materials in the compartments 11 or 12.The inner side and bottom of the receptacle 1, covers 14 and 16 and ring9, are preferably made of bright metallic copper to effect a coppersterilization of the water as it passes over the same to destroy thecolon,

and typhoid bacilli.

The apparatus being assembled and charged as shown in Fig. 1, the waterin the receptacle 1, above the asbestos diaphragm 18, percolates throughthe meshes of said asbestos and comes in contact with and flowsoutwardly on the upper side and upper surface of the cover 16, until itreaches the openings 17, l7,'when said water passes downwardly andthrough the outer perforated periphery of the cover 14: into thefiltering orpurifying composition at the periphery of the outer annularcompartment 12. The water after reaching the periphery of the annularcompartment 12, flows horizontally and in a radial direction through theperforations 10, 10, in the ring 9, through the purifying or filteringcomposition within the central compartment 11, passing down and throughthe screen 5 into drain opening 4: and drain pipe 6, from whence it iswithdrawn as desired by opening the faucet 7.

From the foregoing description of the construction, mode of assemblingand operation of the invention, itwi'll be readily seen that there isevolved a combined 'filter, sterilizer, and purifier, which effects allthe objects and advantages set forth in the statement of the invention,and the water to be purified is made to pass in a circuitous pas sagethrough a large section of cleansing compositions and over sterilizingsurfaces to efiiciently kill all bacteria, bacilli, and germs containedin said water.

While I have shown the preferred form of the casing 1, and thecompartments 11 and '12, as circular and annular in shape, I do notlimit the invention to this particular shape, as, any other --may besubstituted therefor without departing from the spirit of myimprovements.

1 wish it also to be understood that I may use any other form .or kindof purifying materials than those mentioned in the foregoing part of thespecification, such as sand, or silico-carbon, and while I prefer to usethe sand or carbon in the annular compartment 12 and the purifyingmaterial in the central compartment 11, this distribution of saidmaterials may be reversed without departing from my invention; Any othermaterials than asbestos, can be employed for the interwoven cover ordiaphragm 18, if found desirable.
